Hello I have a client who is trying to upgrade from isa 2000 to 2004. Any ideas on the following scenario?

I already configured the New Server and Installed ISA 2004 on the box with all service packs. I thought I could just rename the new ISA box to the Old Isa and save me a lot of changing around. I would also keep the IP's the same as the old one.

We tried the configuration yesterday. Dropped old proxy -deleted name from AD, then brought new Isa up with the exact same settings as it's predecessor. I was able to go out to the internet NOT using the Proxy (which you should not be able to do) and I could see all network computers and AD -but I could not ping the proxy and no one was able to go outside the internet.

ISA 2004 by default is very secure. What I mean by secure is that it locks everything including your internet acccess after a clean install. You need to go to the "firewall policy" to enable them. You will also need to separately enable the dns services, DHCP traffic, you name them, if appropriate.......... In other words, all services or traffic going through the ISA box is blocked.
